PHOTO PRINTING APPARATUS.

To all whom t may concern.:

Be it'known that we, HARRY L. MANS- ifinnn and Brunson Rooms, citizensof the United States, residing at Lucas, in the county of Russell, Stateof Kansas, have in- 'vented a new and useful Photo Printing Apparatus,of which the following is a specification. I

This invention relates to apparatus for l0 printing photographs, itsobject being to provide a simple and efficient mechanism whereby printscan be made quickly and without danger of exposing them to the a tion ofactinic rays.

lVith the foregoing` and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafter'described and claimed, it being understood that changes in the preciseembodiment ot the invention herein disclosed can be made within thescope of what is claimed, without departing from the spirit of theinvention.

In the accompanying drawings, the pre-- ferred form of the invention hasbeen shown.

In said drawings z-Figure 1 is a perspective view of the apparatus, theshutter being shown partly closed and the back board being partlyopened. Fig. 2 is a central vertical section through the apparatus, thefree end portion of the flexible hood being removed. Fig. 3 is a centralhorizontal section through the apparatus. Fig. l is a perspective viewof the removable negative hol ding structure.

Referring to the figures by characters of reference 1 designates abox-like casing the front of which is provided with an opening Qsurrounded by a strip of soft material such as indicated at 3. Thismaterial. is adapted to be contacted by a flat plate et constituting ashutter, said plate being held within a clip 5 which extendslongitudinally of and rotates with a rod 6 journaled in brackets 'l' onthe front of the casing 1. A crank arm 8 extends from one end of the rodand merges into a handle 9.

A spring 10 is secured to the crank arm y and to one side of the casing1 and serves to hold the shutter either pressed tightly against the softmaterial 3 surrounding the opening 2 or else shifted downwardly awaySpecification of Letters Patent.

from the casing so as not to interfere with the admission of light tothe opening Q.

L-shaped brackets 11 are secured to the bottoni of the casing 1 andextend beyond the back or open end of the casing. These brackets areadapted to support a back plate 12 having lugs 13 upstanding therefromand which are shiftable into engagement with spring clips 14k extendingrearwardly from the top of the casing. Then lugs 13 are in engagementwith the clips, the back board 12 is held tightly against the back ofthe casing l. This back board has an opening l5 therein and secured to.said opening is a liexible tube 1G of a. nialerial which will excludelight, this tube having its free end normally contracted by means of anelastic band 17 housed therein. The tube is of sufficient size toreceive an arm of the operator and, when the arm is in position thereinthe elastic band 17 will bind the free end of the tube tightly about thearm so as thus to exclude light from the interior of the tube.

A glass plate 1S is adapted to be seated in one end of the casing 1 soas to extend across the opening Z and detacliably mounted in the casingand back of the glass plate 18 is a backing structure consisting of ablock 19 having top and bottom strips 2O secured thereto and connectedby side strips 2l. An opening E22 is formed within the block 19 and isadapted to be closed by a door 9? which is hinged to the block and isprovided with any suitable means, such as a button 24e whereby the doorwill be held closed within the opening 22. Retaining strips Q5 arepivotally mounted upon the inner faces of the sides of the casing andare adapted, when swung downwardly, to contact with the side strips Q1and thus force the block 19 against the plate 1S or against a negativewhich may be placed upon the back face of said plate.

In using the apparatus the holding devices 25 are shifted upwardly andthe backing shown in Fig. 4; is removed. The negative is then placedagainst the transparent plate 1S after which the backing is reinsertedinto the casing and clamped upon the negative by means of the holdingdevices 25. An ample supply of sensitized paper is then placed in thecasing 1 after which the back board 12 is fastened in place. iOne arm ofthe operator is then inserted into the tube 16 and th-e shutter l isshifted so as to close the opening 2. Door is Athen opened by theoperator, one of the sheets ot.' sensitized paper is placed Within theopening and the door is then reseeured in Closed position so as to Clampthe sensitized material upon the negative. After the parts have thasbeen adjusted, the shutter le is opened by pulling up- .vardlyv onhandle t). ritter the sensitized material has been-.exposed a sutlieientlength o't time, the handle t) .is pushed downwardly and the shutter l*will thus svving to Closed position. Door 223 is then opened, theexposed papei' removed from opening anothe' pieee oft sensitized paperplaced within the opening, and the JforegoingI operation then repeated.ritter a suliieient number of prints have been made` the apparatus eanbe removed to a dark room and the exposed sheets developed asordinarily.

llfhat is Claimed is:-

l. l)hoto-printing apparatus int'luding a 'asing having an exposureopening in one end, a shutter Ytor etosing said opening, a negativebacking device removably mounted within the easing and having anopeningl Yt'or the reception ot sensitized material, a closure tor saidopening, and a `tlexible arma'eeeiving tube connected to one end 0i: theeasing.

2. 3lieto-printing apparatus including a easing having an exposureopening in one wall, a shutter, yielding means Jfor holding the shutternormally across the opening, a backing removabl)7 mounted Within the 'asing for holdingl a negative across the openi ing, said baeliiijig havingan opening to rei eeive sensitized material, a closure movably mount-edwithin the openingr in the backing,

means for detaehablv seouring` the backing against a negative, and aliexible arm-reeeiving tube detaehably connected to one Wall ot' theeasing.

3. Photo-printing apparatus including a easing having an exposureopening in one wall, a transparent plate extending across said opening,a shutter .tor closing the opening, yielding means for holding theshutter in closed position, a backing' detaehabllv mounted within theeasing tor holding a negative against the transparent plate. saidbaeling having an opening tor the reception ot: sensitized material, aclosure vtor the opening in the barking, means `tor fastening saidelosure within the opening, nu'ans Ytor detat'hablyv set'uring thebacking in at'tive position within the easing, and a flexiblearm-reeeiving tube connected to one \vall o'l the easing.

-l-. Photo-printing apparatus ineluding a easing having an exposureopening in one wall, a transparent plate extending aerossl the opening,a t'lip mounted 'tor rotation upon said wall, a shutter extending 'tromthe olip, elastic means tor holdingl the .shutter either in or out otaetive position arross the exposure opening, a handle to' aetuating thestructure, and means \vithin the easingl tor holding a negativay and asensitized material back of the exposure opening.

ln testimony that \ve elaim the foregoing as our own, \ve have heretoa'tlixed our signatures in the presenee ot t\vo witnesses.
